So -3x - 6 = x - 4, ie -2 = 4x so x = -½ and y = -4½
6
x = -3, y = 7
you mean: y= -3x+1 y+x=-3+1 solve -3+1= -2 y+x = -2
the y intercept occurs when x=0 y=3(0) -2 y=-2 the x intercept occurs when y=0 0=3x-2 2=3x x=2/3=.667
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
1) y - 7y = 36 -6y = 36 y = -6 We know that, y = 3x -6 = 3x x= -2 Conclusion, y= -6, x = -2
3x - y = -1 x = -2 3(-2) -y = -1 -6 - y = -1 -y = 5 y = -5
1.5
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
So -3x - 6 = x - 4, ie -2 = 4x so x = -½ and y = -4½
y=x-2
6
Half correct because x = 2 and y = 6
Y=2xx+y=3x+(2x)=33x=3x=1y=2x y=2*1y=2
x = 4 and y = 6
2x+3y=13 3x-y=3 x=2
